This invention relates to a poultry wing feather stripper and has for anobject to provide a device of this character having longitudinallygrooved rolls, the grooves of each roll being staggered relatively tothe other roll to promote a good grip of the rolls on the wing feathersof poultry to pull off the wing feathers without cutting the wingfeathers or breaking off part of the quill in the wing.

A further object is to provide a device of this character having a guardwhich permits entry of the wing feathers between the rolls whilepreventing the operators hands or the wing itself coming into contactwith the rolls.

A further object is to provide a device of this character to which thewing feathers may be fed from the right or the left of the device.

A further object is to provide apparatus of this character which will beformed of a few strong, simple and durable parts, which will beinexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modiiications may be resorted to within the scope of theappended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a front elevation of a poultry wing feather stripperconstructed in accordance with the invention.

Figure 2 is an end elevation of the device shown in Figure 1.

Figure 3 is an enlarged cross sectional view taken on the line 3-3 ofFigure 1 showing the rolls having their grooves relatively staggered.

Figure 4 is a cross sectional view taken. on the line H of Figure 2showing the longitudinal grooves of the rolls of the gear drive of therolls.

Referring now to the drawing, in which like characters of referencedesignate similar parts in the various views, the poultry wing featherstripper comprises a base plate II) which is sup ported on the upperends of spaced frame bars the lower ends of which are secured to aplatform l2 carried by sills [3 adapted to support the device upon afloor or any other suitable support.

The base plate I0 is provided with spaced vertically disposed plates I 4having bearing openings II therein, see Figure 4, to receive the shaftIt of a horizontally disposed roll II. A pair of 55 guide posts Itextend vertically from each plate H, see Figure 3, and support arespective bearing block l8 which is provided with openings 20 toreceive the shaft 2| of a roll 22 whichis superposed upon, and engagesthe roll II.

The guide posts ll of each bearing block are connected at the upper endsby a bar 23 which forms an abutment for a helical spring 24, see Figure2. The spring bears upon the upper edge of the respective bearing blockl9 which latter is provided with a guide lug 25 which enters the baseend of the helical spring. Both helical springs exert pressure upon theupper roll 22 to yieldably hold it in engagement with the lower roll II.

A pair of nuts 26 are threadedly engaged on the upper ends of the guideposts II of each hearing block Is. The nuts engage the ends of therespective abutment bar 23 and may be turned upwardly or downwardly toadjust the tension of the respective helical spring 24.

The shafts l6 and 2| of the rolls are equipped .with respective meshinggears 21 and 28 see Figure 4. The gear 21 meshes with a gear 29, seeFigure 2, carried by a sprocket wheel shaft 30 which is journaled in abearing bracket 3| which is secured to the base plate Ill, see Figure 1.The shaft is equipped with a large sprocket wheel 32 which is connectedby a sprocket chain 33 to a small sprocket gear 34 carried by a pulleyshaft 35 which is journaled in bearing brackets 38 carried by the framebars H, see Figure 1. A belt 36 is trained over a pulley 31 carried bythe pulley shaft, and over a pulley 38 carried by the shaft 39 of anelectric motor 40 which is supported on the platform l2. Through themedium of the drive means just described the rolls are rotated to feedthe wing feathers of poultry, such as turkeys and other fowl between therolls to pull out the feathers from the wings.

The rolls l1 and 22 are of special construction so as to effectivelypull out the feathers without breaking the feathers or leaving part ofthe quill in the wings. For this purpose the rolls are provided withrespective longitudinal grooves 4| and 42, see Figures 3 and 4. Thegrooves of the rolls are staggered relatively to each other so that thegroove of one roll registers with the cylindrical surface between twogrooves of the companion roll. This construction permits the rolls toeffectively grip the feathers without slipping and pull the feathersfrom the wing during rotation of the rolls. Furthermore each groove isarcuate in cross section, the curvature being about onethird of acircumference, or degrees. This particular contour of groove has beenfound in practise to promote self-cleaning of the grooves. A guard 43 isdisposed over the front sides of the rolls and comprises spaced rods 44connected together at the upper ends by a bar 45 which is fixed to thefront guide posts 18 of both bearin plates l9, see Figure 3. The lowerends of the rods are connected together by a bar 46 which is secured tothe plates M by screw bolts 41. The bar 46 is provided with an arcuateskirt 48 which extendsforwardly over the bar and beyond. the bar. Thespaces between the bars permit the wing feathers to enter between therolls, while also the bars prevent contact of the operator's hands withthe rolls.

From the above description it is thought that I the construction andoperation of the invention will be fully understood without furtherexplanation.

What is claimed is:

i. A poultry wing feather stripper comprising a frame, a pair of rollson the frame, one of'the rolls being spring pressed to yieldably engagethe other roll, both rolls being formed with spaced longitudinalgrooves, the grooves of one roll being staggered relatively to thegrooves of the other roll so that'a groove of one roll will registerwith the cylindrical surface between twogrooves of the'other roll duringrotation of the rolls, and means for rotating the rolls.

2. A poultry wing feather stripper comprising a frame, bearing platesrising from the frames, a roll having a shaft journaled in said bearingplates, spring pressed bearing blocks supported on top of the bearingplates, 9. roll having a shaft iournaled in said bearing blocks, meshinggears on said shafts for rotating the first-mentioned roll when thesecond-mentioned roll is rotated, and means for rotating saidsecond-mentioned shaft, said rolls having respective cylindricalsurfaces provided with longitudinal grooves, the grooves of one rollbeing relatively staggered to the grooves of the other roll.

3. The structure as of claim 1 and in which said grooves are arcuate incross section and are substantially 120 degrees of a circumference indepth so as to be self-cleaning.

4. A poultry wing feather stripper, comprising a frame, a pair ofyieldingly engaged rolls on the frame, both rolls being formed withspaced long-itudinal grooves, the grooves of one roll beingstaggeredrelatively to the grooves of the other roll so that a groove ofone roll will register with g the cylindrical surface between twogrooves of the a other roll during rotation of the rolls, and means
